City of Campbell River

The City of Campbell River operates the Norm Wood Environmental Center wastewater treatment plant. This treatment plant provides services to 38,000 residents through secondary (biological) treatment, clarification, and aerobic digestion.  Approximately 10,000 m3 of liquid biosolids (350 dry tonnes) are used annually to fertilize City-owned hayfields with a pivot irrigation system on a parcel of agricultural land adjacent to the plant.

SYLVIS has provided technical and qualified professional support for the City’s biosolids management program since 2015. SYLVIS manages the application program in a series of irrigation zones, providing the City with detailed irrigation management information based on vegetation requirements and modelling of precipitation, irrigation, and evapotranspiration. Other work on this project includes preparation and submission of biosolids Land Application Plans, regular site inspections throughout the application season, coordination of the daily biosolids applications with City staff, sampling of soil and groundwater, weed surveys and management recommendations, and preparation of a compliance report following biosolids applications.

Given the long history of use of this site for biosolids applications, continued use of the site requires detailed environmental monitoring and intensive management of biosolids and biosolids nutrients in order to meet all regulatory criteria and best management practices. SYLVIS provides expert advice for ongoing success and sustainability of the City’s biosolids management program. SYLVIS is currently providing services to the 2020 program.
